Can anyone explain why the new ISOCoated_v2_ECI
profile looks like a 'real world' press target as
opposed to a mathematically generated one when viewed
in Apples Colorsync utility?
To see what I mean, load 'Colorsync Utility.app' not
by double clicking on a profile file, but from the
application in the 'Applications:Utilities' folder
under OSX. (For some reason you get a different window
if you open the app by double clicking on a profile!)
When the application opens you should see a main
window with a list of the profiles installed on your
machine down the left hand side and a blank space on
the right side.
When you select a profile you get a 3D representation
of the colour space, you can navigate around the image
using the mouse, click and drag. By clicking on the
little grey down arrow in the top left of the 3D
display, you can hold the profile for comparison, then
select another profile from the list.
The ISOCoated_v2_ECI profile matches our Press/Proofer
calibration profiles almost exactly, but when you view
the previous ISO & Forga27 profiles the 3D diagram is
very different. Looking much more like it's a purely
mathematical model without the 'blobbyness'
(technical term!) of the new ISOCoated_v2_ECI.
Does anyone know what's causing this?
Is it the software used to create the profile?
Is it that the new ISO profile is actually created
from a printed sheet of paper instead of a
mathematical formula from a set of 'ideal' lab colours
and black generation parameters?
Thanks
